“…Transient overexpression of these R2R3-MYBs in Phalaenopsis verified that they can promote anthocyanin accumulation, and these PeMYBs could activate the expression of downstream structural genes. VIGS and transient overexpression of PeMYB4L, a member of R2R3-MYB verified its role in regulating anthocyanin biosynthesis in Phalaenopsis [ 137 ]. In Cattleya , transient overexpression of its two R2R3-MYBs ( RcPCP and RcPAP ) in a Phalaenopsis hybrid showed elevated expression of structural genes involved in carotenoid biosynthesis and anthocyanin biosynthesis, respectively, resulting in yellow or red pigmentation in Phalaenopsis ’s perianth [ 138 ].…”

“…Comparative transcriptomics of Pleione showed a MBW protein complex formed by PlMYB10 , PlbHLH20 , or PlbHLH26 and PlWD40–1 can repress the expression of flavonol synthese ( FLS ), the key structure gene in the anthocyanin biosynthesis pathway that contributes to color formation, resulting in color variations in wild populations [ 141 ]. Transient overexpression of a bHLH protein PeMYC4 plus a R2R3 MYB PeMYB4L showed a negative regulation of the anthocyanin accumulation by inhibiting the expression of structure gene chalcone synthase ( CHS ) [ 137 ]. Characterization of the structure genes involved in the anthocyanin biosynthesis has also been extensively studied in orchids.…”

Orchidaceae is one of the largest, most diverse families in angiosperms with significant ecological and economical values. Orchids have long fascinated scientists by their complex life histories, exquisite floral morphology and pollination syndromes that exhibit exclusive specializations than any other plants on earth. These intrinsic factors together with human influences also make it a keystone group in biodiversity conservation. The advent of sequencing technologies and transgenic techniques represents a quantum leap in orchid research, enabling molecular approaches to be employed to resolve the historically interesting puzzles in orchid basic and applied biology. To date, 15 different orchid genomes covering four subfamilies (Apostasioideae, Vanilloideae, Epidendroideae and Orchidoideae) have been released. These genome projects have given rise to massive data that greatly empowers the studies pertaining to key innovations and evolutionary mechanisms for the breadth of orchid species. The extensive exploration of transcriptomics, comparative genomics, and recent advances in gene engineering have linked important traits of orchids with a multiplicity of gene families and their regulating networks, providing great potential for genetic enhancement and improvement. In this review, we summarize the progress and achievement in fundamental research and industrialized application of orchids with a particular focus on molecular tools, and make future prospects of orchid molecular breeding and post-genomic research, providing a comprehensive assemblage of start-of-art knowledge in orchid research and industrialization.
